The full patient identifier is (b)(6).The customer did not supply patient demographics such as weight, ethnicity or race.The access progesterone reagent was not returned for evaluation.No other patient results were called into question and no specimen was remaining from the patient.No investigative testing could be performed.No error messages or issues with other assays were reported in connection with the event.There were no reports of hardware interventions performs or hardware parts replaced.Available system performance indicators of passing system check and precision study did not demonstrate an issue with the system.In conclusion, the cause of this event cannot be determined with the available information.There is malfunction as original result is discordant with 1 replicate measurement of the same specimen on another methodology and patient clinical file.

On (b)(6) 2021 the customer reported obtaining false elevated progesterone (access progesterone) results for one patient involving the laboratory's access 2 immunoassay analyzer (serial number (b)(4)).On (b)(6) 2021, an unexpected progesterone result of 2.34 ng/ml was generated for one patient sample.The sample was run the day after on an alternate methodology (roche elecsys) and a low progesterone result of <0.1 ng/ml was obtained (roche progesterone reference range is 0.1-0.9 ng/ml).The patient was redraw and retested on (b)(6) 2021 with a progesterone result of 2.09 ng/ml.The sample was run the same day on an alternate methodology (methodology unknown) and a low result of 0.67 ng/ml was obtained.The customer reported the progesterone results run on alternate methodologies aligned with the clinical presentation of the patient.Due to the abnormally high results, the patient has had their ivf cycle cancelled twice.Two (2) medwatch reports will be generated to address both ivf cycle cancelled.Medwatch number ¿2122870-2021-00088¿ will address the ivf cycle cancelled on (b)(6) 2021.No error messages or issues with other assays were reported in connection with the event.There were no reports of hardware interventions performs or hardware parts replaced.System check passed on (b)(6) 2021.Calibration passed on (b)(6) 201 using reagent lot 922932 and calibrator lot 922326.Sample information such as sample collection tube used, centrifugation time and speed, storage or handling was not provided by the customer.There was no report of sample integrity issues.
